Can u help me on this pl

B)

Step-by-step explanation:

To find the expression equivalent to , we must simplify the given expression. This can be done by applying an exponent rule:

In the context of our problem, we would have:

Therefore, when that exponent is distributed, we get:

Simplified, we have:

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
